Webbför 7 timmar sedan · Analytical sensitivity (limit of detection [95% probability]) was characterized with respect to tumor content by expected variant allele frequency and was determined to be 0.07%-0.17% across five tumor cases and 0.51% for the lymphoid neoplasm case. Test specificity was 99.3% (95% confidence interval, 98.6–99.7%). chip fritzbox loginWebb5. Independent trials that result in a success with probability p are successively performed until a total of r successes is obtained. Show that the probability that exactly n trials are required is n−1 r −1 pr(1−p)n−r. Solution: When ”a total of r successes is obtained” we have r − 1 successes before the last trial.
